We are definitely hearing a lot about this stuff from Google and other tech companies lately. I don't know what we can reliably infer from the absence of that kind of news what that says about other industries.
My intuition is that workplace sexual harassment has been rife in all aspects of human endeavor since the dawn of time. The "boss screwing the secretary" trope isn't exactly a new one. It may be that we're seeing a combination of things:
1. Thanks to the #metoo movement, people who get harassed now have enough power to actually be able to stand up and cause the person they accuse to face some scrutiny. Before, it was just swept under the rug. "Boys will be boys", "that's what you get for dressing like that", "you should have known better to stay late at work with him", etc.
2. The very rapid rise of tech as a cultural dominator makes them a prime actor in our moral narratives. The average person sees a handful of giant tech companies dramatically changing the way we all live, and they naturally want to know if they are a force for good or evil. Those kinds of journalistic narratives sell.
For all we know, sexual harassment could be 10x worse in the insurance industry but we won't know because who wants to read articles about the insurance industry?
3. There's also the obvious bias that if something happens too much, it ceases to be news. "Newsworthiness" is a combination of significance and novelty. The former is where good investigative journalism can show the scope of a sweeping hidden problem. The latter is the old "dog bites man" isn't news but "man bites dog" is. It's easy to mistake the latter for the former and assume that something being reported indicates a trend, when really it indicates the exact opposite.
So, it may be that things really are worse at Google than at other places, but I don't know if we can rely on the presence of news articles to judge that.
